Asked in Meteorology and Weather, Atmospheric Sciences

What instrument measures atmospheric pressure?

The instrument, most commonly used in science, is a barometer. Related Information: The word, Barometer, is derived from baro, meaning weight or pressure, and meter, meaning measuring device. Barometers can be either analog or digital. The traditional analog barometer is known as an aneroid barometer. These are the round chrome or brass type that you would normally see on the bridge of a ship, many times accompanied by clock, temperature, and/or humidity gauge. For an accurate and reliable aneroid barometer, you should expect to pay $249.00...

What instrument measures humidity?

The instrument that measures humidity is called a hygrometer. A hygrometer is an instrument that measures relative humidity in the air. One common kind of hygrometer is a psychrometer, a device that measures the temperature of a wet bulb and a dry bulb simultaneously. The wet bulb should be cooler (if it's above freezing), because water evaporates from the bulb, taking energy with it. If the air is more humid, the evaporation is slower, so the bulb is closer to the dry bulb's...

Asked in Meteorology and Weather, Atmospheric Sciences, Temperature

What is the hottest air temperature ever recorded on earth?

The world's highest recorded air temperature is officially recognized by the World Meteorological Organization as 134°F (57.6°C) recorded at Death Valley, California, USA on 10 July 1913. Note that this is in recorded history. Higher temperatures have occurred, of course, at different times during the 4.55 billion years of Earth's history. Related Information: El Azizia, Libya, held this record for 90 years, after recording a temperature of 136°F (58°C) on 13 September 1922. It was coincidentally also on 13 September of 2012 that this record...

Asked in Atmospheric Sciences, Aurora Borealis and Aurora Australis

What causes the aurora borealis?

Auroras are caused by radiation from the sun, called solar wind, interacting with Earth's magnetic field. When magnetic storms occur on the Sun, electrically charged particles (ions) from the corona and solar flares are added to the solar wind produced by the corona. Solar charged particles from the sun, which are normally radiated into space, sometimes get caught in the Earths magnetic field as they come into the upper atmosphere they react with other gases and produce coloured lights. The Earth's magnetic field...

What are two facts about the troposphere?

- The troposphere is the lowest part of Earth's atmosphere. - It contains about 75% of the atmosphere's mass. - It also contains about 99% of the atmosphere's water vapour and aerosols. - Most weather phenomena occur in the troposphere. - It ranges in thickness from 8km at the poles to 16km over the equator. ...

Asked in Ozone Layer, Atmospheric Sciences

In which layer of the atmosphere is ozone found?

It is in the stratosphere, located 8 to 50km above sea level. The ozone layer surrounds the earth, meaning that it's wrapped around earth. The altitude varies with latitude as well, placing the stratosphere and the ozone layer closer to the Earth's surface over the poles. The highest concentration of ozone is in the lower stratosphere, also called the tropopause, and the ozone here is called the ozone layer. Ozone is also found in the lower atmosphere, also called the troposphere, and the...

Asked in Atmospheric Sciences, Ozone Layer

What are the causes of the hole in the ozone layer?

Briefly: CFCs and similar man-made gases break down the ozone in the stratosphere allowing in harmful ultraviolet radiation. The ozone hole happens mostly in Antarctica where four months of winter darkness create ideal conditions for the destruction. Ozone is a protective layer in the upper atmosphere. It is formed, when oxygen molecules absorb short wavelength ultra violet radiations from the sun. Ozone is mostly destroyed by the free radicals in the atmosphere. When compounds like CFCs (chlorofluorocarbons) are released, they are dissociated by sunlight into chloride...

Asked in Astronomy, Atmospheric Sciences, Aurora Borealis and Aurora Australis

Are the rainbow and the Aurora borealis similar?

Rainbows and Aurora are completely different phenomena and the colours produced through completely different methods. Rainbows happen when white light passes through a prism (rain drops act as a prism). The white light is made up of 8 distinct colours. We all probably remember the phrase Richard Of York Gave "Courageous" Battle In Vain to remember the colours. Red Orange Yellow Green Cyan Blue Indigo Violet are the colours we see. The different colours separate because they all have different energy. The less...

How can you create a partial vacuum at home?

Turn on the vacuum cleaner, this is a partial or imperfect vacuum.

Asked in Meteorology and Weather, Atmospheric Sciences, Meteorologists

Why is it important to study weather?

It is important so that weather can be predicted in advance. Just about everyone everyday is affected by weather, and often make decisions based on what the weather will be. There is a financial element to this as well, with most forms of commerce in some way affected. In fact, the US's National Weather Service is located within the Department of Commerce for this reason. If weather could not be predicted, many billions of dollars would be lost each year as a...

Asked in Atmospheric Sciences, Temperature

Most meteors burn up in the even though it's the coldest layer?

Mesophere. They don't burn up because of the ambient air temperature, but because of the heat generated by friction - they are moving incredibly fast. ...


Asked in Clouds, Atmospheric Sciences

Why is there more pressure in lower atmosphere?

Air molecules are piled up on each other in our atmosphere. The lower the air molecules, the more weight they're under causing more pressure. Higher up the molecules have more space to move around in resulting in lower pressure. ...


Asked in Atmospheric Sciences, Water Cycle

What are the five parts of the water cycle?

1: evaporation 2: transpiration (plants only) 3: condensation 4: precipitation 5:run off/ground water The water cycle is the earths way of reusing water. water from oceans and such evaporates and condenses to form clouds as clouds gain more water until they are unable to hold it all then precipitation occurs (think rain). then the water flows back to the oceans via rivers and such. ...

Asked in Atmospheric Sciences

Why does air pressure decrease with an increase in altitude?

Air pressure decreases with an increase in altitude because the higher you are, the less air there is above weighing down upon you. This is because air behaves much like water. If you are swimming, the deeper you dive, the greater you feel the pressure build, because there is more water above weighing down upon you. It is the same with air. On top of a mountain, air pressure is lower because the column of air above you is shorter. At sea level, the...

Asked in Atmospheric Sciences

Why does the troposphere contain the most mass?

The troposphere is relatively dense because of the force of gravity on the gas molecules it contains. The outer layers of Earth's atmosphere are closer to the vacuum of space and have comparatively few of the gas molecules that give the troposphere its mass. ...

Asked in Meteorology and Weather, Atmospheric Sciences

Why does the temperature increase as you go higher in to the stratosphere?

Short answer: Absorption / emission of light. The atmosphere gets thick enough that the oxygen and nitrogen there absorb UV-C and more energetic light, ozone absorbs UV-B (from above) and some infrared (both from above and below, ozone is a greenhouse gas). Where there is little ozone, there is little indication of temperature. ...
